Abstract

This application relates to a metropolitan area Internet of Things (IoT) system and its security authentication method, apparatus, and storage medium. The system includes a perception layer for sensing the state of target objects and collecting data via sensor terminals, then forwarding the sensed data to an IoT gateway; a network layer for transmitting the received sensed data via a transmission network; a platform layer for parsing and forwarding the sensed data that has passed access security authentication based on a network controller; and an application layer for implementing IoT application services based on the parsed sensed data. The IoT gateway includes an access authentication module for obtaining a session key before the sensor terminal accesses the platform layer through the IoT gateway. The IoT gateway performs access security authentication on the sensor terminal at the physical layer based on the session key. This application improves the communication resource consumption of IoT security authentication methods and enhances system scalability.
